TechBytes: iPad 3G Launch Date

April 21, 2010— -- The next wave of iPads is about to arrive. Apple says a version of the device that can run on cellular networks will be in stores and homes April 30. The 3G-versions of the iPad cost $130 more than the Wi-Fi only models that went on sale earlier this month. The new models can connect to AT&T's mobile data network, with users able to pay for the data plan on a month-by-month basis.

The web is constantly changing and articles are being posted one day and removed the next. A new bookmarking program called iCyte guarantees that you'll always be able to see what you save when you go back to a page, even if the page has been deleted. The Wall Street Journal's Katie Boehret said it's a very useful tool. "I really liked using this because I find myself browsing the web a lot and then I have a lot of things I don't get to finish reading and then I sort of forget where those addresses are and I don't necessarily get time to go back to them," she said. You can read Boehret's full review on the Wall Street Journal's website.
